Kanjani ukuhlola ukuthi komoya inzwa unephutha?

komoya inzwa kumelwe anqume inani emoyeni edonswa imoto. Ngokusekelwe idatha etholwe kusuka kudivayisi, le control unit injini sinquma inani fuel injected amasilinda.

"Izimpawu" olungenzeka a ukungasebenzi flowmeter:

• Engine "akaphinde asibalele" isivinini lutho.
• Kwandisa petrol.
• Ophephela ixhunyiwe okungazelele noma ayixhunyiwe nhlobo.
• Ijubane injini kungenziwa kungagcini 3000 ngomzuzu.
• Mhlawumbe umkhawulo isivinini. Ngokwesibonelo, umshini kungenzeka ucishe asebenzayo isivinini inzuzo ku-100 km / h, okwathi ngemva kwalokho ukusheshisa iyama noma iba kancanekancane.
• Umshini ilahlekelwa amandla kakhulu.

Ukuhlola kwe-komoya inzwa senziwa usebenzisa ama-apharathasi ekhethekile - futhi oscilloscope compressor. Kwenzeka bephoqeleka okuphakelayo emoyeni ukusakaza isignali inzwa nebanga yokulandelela. Njengoba kunqunywa ngesikhathi lapho Ukushisa lifudumeza befilimu inzwa.

Lapho yokuqinisekisa isignali okukhipha ngokuyinhloko kulinganiswa ngesikhathi lithatha inqubo shintsho ngesikhathi ukushintsha phezu ukuthungela. Esimeni lapho komoya inzwa kuyinto serviceable, ukubaluleka okuholela ngeke ukundlula millisecond ambalwa. Ukuze kwandiswe Ukushisa nesikhathi inzwa kungaholela ezingcolisa zazo imali kwi inzwa. Kulokhu, inqubo shintsho kungathatha amashumi noma amakhulu millisecond.

Ngaphezu kwalokho, voltage ukubaluleka kulinganiswa ngesikhathi ukugeleza komoya ilingane no-zero. Ukuze test kudinga ukuthi injini samiswa, kodwa ukuthungela kumele zifakwe. I evamile okukhipha voltage Inani khona zero komoya zingahluka futhi incike emoyeni ukugeleza inzwa okuyinto imodeli isethi.

Ngemva kwalokho, esiphezulu voltage ukubaluleka kulinganiswa ngesikhathi Snapping abukhali. Kulesi umshini injini kumele okungenani izinga lokusebenza kanye ukudluliswa ungaphakathi hlangothi. Ngesikhathi sesivivinyo lo mpintsha wawuvula ngesankahlu umnyango isikhathi esingeqile ngomzuzwana. Lokhu isheke kungenzeka kuphela izinjini asemkhathini (ngaphandle compressor kanye ophephela) futhi, uma isinyathelo namafutha is athutha kuhambisane valve mpintsha (nge iziyisikhombisa noma ikhebula).

Lapho injini isebenza ngaphandle umthwalo ngesikhathi idling isivinini, emoyeni ekhona le ezininginingi engayitholi esibhedlela. Uma komoya inzwa ayilungile, voltage kufanele esikhathini esifushane idlule uphawu 4V. Uma inzwa ingcolile kakhulu, inzwa kungaba asabela eside. Ngakho ostsilogrammy "eshelelayo". Ngenxa ukungcola encishisiwe amalahle isignali samanje inzwa, esehlisa supply fuel ku amasilinda. Ngakho-ke, lapho ukusika peregazovke isignali voltage inzwa akanayo isikhathi ukufinyelela amanani esiphezulu.

Uma kwatholakala ukuthi une-ukungasebenzi sina zedivayisi, kufanele omunye esikhundleni sakhe. Balungise MAF inzwa kwenziwe.
